Support for bind parameters

[Metrol]

Queries that include text like :personid are usually expecting this marker to be giving a bound parameter when executing.

Example:

SELECT * FROM people WHERE personid = :personid;

That "other" database console out there actually handles this pretty well. Just before executing, the user is prompted for all the values of the parameters in the query. It also has a keymap to manually assign those values. Mentioning as a point of reference only.

For my little world, this is a show stopper. Any query that I'm working on that will later be put into code will most certainly have a number of bind parameters in them. I would think this would impact others, but I didn't see any other issues dealing with this.
